摘要: The invention relates to a process for the preparation of compounds of formula (I) ##STR1## wherein R.sup.1 stands for hydrogen or the group COR.sup.2, whereinR.sup.2 stands for a straight or branched chained alkyl having 1 to 8 carbon atoms optionally substituted with phenyl, naphthyl, tetrahydronaphthyl or m-phenoxy-benzyl, cycloalkyl having 3 to 6 carbon atoms optionally substituted with one or more straight or branched chained alkyl or alkenyl having 1 to 6 carbon atoms, phenyl or naphthyl.The compounds of formula (I) are prepared according to the invention by(a) reacting esters of formula (II) ##STR2## wherein X stands for chlorine or bromine andR.sup.2 has the same meanings as defined above with a phenol alkali metal salt and(b) if desired converting the diphenyl ethers so obtained to a specific compound of formula (I), m-phenoxybenzyl alcohol by the hydrolysis of the ester group.
